Abstract
The utility model discloses a kind of engine hydraulic start stop system, comprise the power assembly of motor, oil hydraulic pump formation, described power assembly sets up hydraulic launch motor, and hydraulic launch motor and engine mechanical are in transmission connection, in order to ato unit; Hydraulic pump outlet connected electromagnetic valve group and accumulator, described solenoid valve group is when engine work, and the accumulator that conducting is connected with hydraulic pump outlet, to accumulator pressurizing; When motor is in idling and car load is in wait state, kill engine; When car load restarts work and needs engine start, solenoid valve group turn-on accumulator and starting motor, drive oil hydraulic motor ato unit.Application the technical solution of the utility model, can save engine consumption, reduces the operating cost of machinery.
Description
Technical field
The utility model relates to operating device, is specifically related to a kind of engine hydraulic start stop system.
Background technique
Traditional motor and oil hydraulic pump assembly comprise motor, oil hydraulic pump, and driver can manually boot motor or kill engine, but motor can not open and close automatically.Traditional working procedure is that motor is in idling mode when car load is in wait state.Above-mentioned situation causes engine consumption to be wasted, and increases operating cost.
Model utility content
The purpose of this utility model is to provide a kind of engine hydraulic start stop system, overcome native defect, scheme of the present utility model is as follows: a kind of engine hydraulic start stop system, comprise the power assembly of motor, oil hydraulic pump formation, described power assembly sets up hydraulic launch motor, hydraulic launch motor and engine mechanical are in transmission connection, in order to ato unit; The outlet of described hydraulic launch motor is connected with fuel tank, entrance is connected with solenoid valve group, in the inside of starting motor, there is one-way valve, motor is when normally working, the entrance of starting motor got back to by the hydraulic oil that starting motor exports by one-way valve, hydraulic oil circulates between starting motor and one-way valve.Hydraulic pump outlet connected electromagnetic valve group and accumulator, described solenoid valve group is when engine work, and the accumulator that conducting is connected with hydraulic pump outlet, to accumulator pressurizing; Described solenoid valve group comprises a topping up electromagnetic switch valve, startup solenoid valve, a relief valve and a manual switch valve, and described topping up solenoid valve connects hydraulic pump outlet and accumulator, for accumulator topping up; The affiliated solenoid valve that starts connects accumulator and starting motor, for driving starting motor ato unit; Described relief valve connects accumulator and fuel tank, for limiting the highest supercharging pressure of accumulator; Affiliated manual switch valve connects accumulator and fuel tank, for laying down the pressure inside accumulator before maintenance or dismounting.When motor is in idling and car load is in wait state, kill engine; When car load restarts work and needs engine start, solenoid valve group turn-on accumulator and starting motor, drive oil hydraulic motor ato unit.
Application the technical solution of the utility model, can save engine consumption, reduces the operating cost of machinery.
Accompanying drawing explanation
Fig. 1 is the utility model hydraulic structure schematic diagram.
Embodiment
Below with reference to the drawings and specific embodiments, the present invention is described in further details.
Traditional motor and oil hydraulic pump assembly comprise motor, oil hydraulic pump.The utility model, in traditional motor and oil hydraulic pump assembly 1, increases following element: starting motor 2, accumulator 5 and solenoid valve group 6,
Hydraulic launch motor and engine mechanical are in transmission connection, and oil hydraulic pump 1 exports connected electromagnetic valve group and accumulator,
When engine work, the solenoid valve group 6 be connected with hydraulic pump outlet connects oil hydraulic pump and accumulator, to accumulator pressurizing.When motor is in idling and car load is in wait state, kill engine.
When car load restarts work and needs engine start, solenoid valve group turn-on accumulator and starting motor, drive motor ato unit.
Application the technical solution of the utility model, can save engine consumption, reduces the operating cost of machinery.
Above the utility model is described in detail; for one of ordinary skill in the art; according to the thought of the utility model embodiment; all can do respective change according to actual demand; as long as have employed the various improvement that technical solutions of the utility model are carried out, all within protection domain of the present utility model.
